Consistent Mesh Aperture Diamond Metal Lath Ideal for Stucco Over Wood Sheathing
Precision-spaced diamond apertures maintain +/-0.02" tolerance across rolls, engineered expressly for stucco adhesion over dimensional wood sheathing—eliminating substrate telegraphing and cold-joint ghost lines in coastal residences and cedar-clad commercial façades. Its rigidified "anti-curling" flanges combat wood movement under seasonal thermal cycling while GS-38 zinc-aluminum alloy strips resist vapor-driven corrosion, achieving ASTM C1063 Category IV shearing strength at critical joist interfaces. Weatherization crews standardize this pattern for timber-frame retrofits where traditional hexagonal mesh permits blistering, with wind-uplift ratings exceeding 170 mph via third-party Miami-Dade NOA testing on engineered wood panels.
Pacific Northwest specialty contractors and Florida hurricane-code builders specify this aperture-controlled matrix when securing three-coat stucco over plywood or OSB substrates prone to differential expansion. Integrated capillary breaks mitigate efflorescence at weep screed transitions while CRRC-certified thermal reflectivity reduces sheathing heat saturation in desert climates. Request region-specific galvanic isolation guidelines for mixed-material assemblies or utilize our laser-calibration gauges to verify mesh conformance before plastering—supported by lifetime delamination warranties with optional ASTM E2273 moisture migration testing protocols.

FAQ
1. What is expanded metal lath used for?
It is mainly used as a base for stucco or plaster on walls, ceilings, and soffits. The mesh provides excellent keying for cementitious materials.
2. Does your product meet U.S. and Canadian standards?
Yes. Our expanded metal lath complies with ASTM C847 and CSA standards, and is ICC-ES(5419) certified, ensuring approval for a wide range of North American construction projects.
3. Do you offer different types and weights?
Yes. We offer various rib profiles, mesh patterns, and weights such as 1.75 lbs, 2.5 lbs, and 3.4 lbs per sheet to suit different application needs.
4. What is your MOQ and lead time?
Our minimum order is 2 pallets (total 1,000 sheets, 500 sheets per pallet). Typical lead time is 15–20 working days, depending on order volume and requirements.
5. How is the product packaged for export?
We use standard palletized packaging for safe and efficient container loading and unloading. Custom labels and weather-resistant wrapping are also available upon request.
